The snaffle bit is made in standard sizes, ranging from 3½ to 6½ inches. It must be the correct size and type of mouthpiece for the horse.
The snaffle bit is attached to the cheekpieces and reins, providing control whilst riding or handling the horse. From the side, the bit should create 1-2 wrinkles in the corners of the horse’s mouth.
If the bit is fitted too high: it will cause discomfort or sores on the horse’s mouth.
If the bit is fitted too low: it will not work on the correct areas of the mouth making it ineffective. It may also bang on the teeth, causing pain, or the horse may excessively play or put their tongue over the bit.
If the mouthpiece is too thick: thick mouthpieces can take up too much room in the mouth, especially if the equine has a big tongue. A thinner mouthpiece may provide more comfort.
If the mouthpiece is too thin: a thin mouthpiece can be too harsh on equines with a fine, sensitive mouth. A thicker mouthpiece may offer more comfort as it will distribute the pressure more evenly.
When the bit is pulled out to one side of the horse’s mouth, there should be a ¼ inch over-hang (a rough guide is to fit your little finger in the space).
If the bit is too long: it will not work on the correct areas, create too much movement and could cause any links in the middle of the bit to catch the sides of the horse’s mouth.
If the bit is too small: it will not work on the correct areas and pinch the sides of the mouth.
Both can cause discomfort, sores and rubs on the horse’s mouth.
